有限单元法从20世纪50年代至今,经过几十年的发展,不断开拓新的应用领域,其范围已经由杆件结构问题拓展到了弹性力学乃至塑性力学问题,由平面问题扩展到空间问题,由静力学问题扩展到动力学问题和稳定性问题,由固体力学问题扩展到流体力学、热力学和电磁学问题.
本论文就是基于有限元基本原理,利用ansys软件就象鼻岭水电站拱坝建立有限元模型,并利用该软件的后处理器提取需要的关键部位的应力值,应力、位移云图等,对象鼻岭拱坝进行多工况静动力分析.提取第一、第三主应力及顺河向、大坝走向及竖直向位移,分析大坝的计算结果及安全性.对比研究象鼻岭拱坝的振型及应力响应结果,掌握拱坝的动力特性,参照规范分析各种荷载因素的影响,对各种工况进行组合分析,从而得到坝体可能达到的最大应力值,分析拱坝的抗震薄弱环节.
到目前为止,拱坝体型设计仍以拱梁分载法为主要手段,其主要原因是有限元成果与所采用的单元形式和单元划分有很大关系,而且近基础部位存在明显的应力集中,这对结果的评价及应力控制标准的确定带来了困难.本次设计采用了有限元等效应力法,已解决上述提到的应力集中问题.

Finite element method from the 1950s,after decades of development,and constantly develop new applications and its scope of rod structure has been expanding to elastic mechanics and plastic mechanics problem,by plane problems to expand space by static,dynamic problems and issues to expand by solid mechanics,stability problem to expand fluid mechanics,thermodynamics and electromagnetism.
This paper is based on the basic principle of finite element software ansys,the elephant nasal ridge hydropower dam,a finite element model and using the software after extraction of key parts of the processor to stress value,stress and displacement map,object nasal ridge dam in the static and dynamic analysis of working.Extracting the first and third principal stress along the river,and from the vertical displacement and dam to dam,the calculated results and safety.The comparative study of arch dam strikeout ridge stress response,and the dynamic characteristics of the arch dam,according to standard analysis of various factors that influence the load of combination of analysis to obtain the maximum stress may achieve dam,the analysis of arch dam seismic vulnerabilities.
So far,the arch design still GongLiang points in law as main means,the main reason is the result of finite element used to have very big concern with unit division,and nearly foundation has obvious stress concentration,the results of the evaluation and control of the standard.This design using the finite element method,the equivalent stress of the above-mentioned has solved the problem of stress concentration.
